I had a melt down of a few wires in the breaker box
in the house. I rewired that and now have lights in hottub
but the groung fault breaker keeps kicking it off. I would
turn on heater before and it would kick it off. Now it has
220 power and lights work but nothing else. I had the
heater out and they say it works. I had the motor checked
out and its good. Its a 1989 coleman horizen tub. any ideas?

Was the tub in good working order before the "melt down"? Is the ground fault breaker at the tub or the one in the main breaker box? Was the ground fault tripping before when you turned it on?
